SHAKING ATTACHMENT FOR ROCKING GRATES.

SPECIFICATION-forming part of Letters Patent No. 456,244, dated July 21,1891.

Application filed October 15,1890. Serial No. 368,218. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM L. MORRIS, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Shaking Attachments forRocking Grates, of which the following, with the accompanying drawings,is a specification.

This invention relates to certain new and useful improvements in shakingattachments to rocking grates.

The invention consists in the peculiar construction, arrangement, andcombinations of the various parts, all as more fully hereinafter setforth, and pointed out in the claim.

Figure 1, Sheet 1, is a top plan of the attachment detached, showing thehandle as drawn out in position for rocking the grates. Fig. 2, Sheet1,is a similar view with the handle pushed in. Fig. 3, Sheet 2, is aside elevation showing manner of pivotally hanging the vibratingbracket. Fig. 4, Sheet 2, is a sectional view of the ash-pit section ofthe boiler, showing the shaking attachment in position and attached tothe pendants of the rocking grates. Fig. 5, Sheet 1, is a section on theline .2 z of Fig. 2. Figs. 1, 2, 3, and 5 are drawn to a uniform scale,while Fig. 4 is materially diminished in size.

In the accompanying drawings, which form a part of this specification,Arepresents the side bar of a rocking grate of any known construction,the rocking sections of which are provided with the pendants a, andwhich latter are connected together by a shakingstrap B in any suchmanner that the said grates may be simultaneously operated.

0 represents the front bearing-bar, which supports the front ends of thegrates. D is a hanger depending from said bearing-bar C, and it isprovided with a pin E, upon which is pivotally mounted the vibratingbracket hereinafter described.

F is a vibrating bracket, which is pivotally hung upon the pin E, thepin passing through the opening, which latter gradually increases insize from its longitudinal center outward, so as to allow the bracket tohave a rocking motion upon said pin and to prevent binding or catchingin theoperation of .the device.

The cored arm F is preferably provided at or near one end withdiametrically-opposite bosses Ft, by means of which the bracket F may bepivotally hung in the end of a yoke G, which is secured upon the end ofa hollow connecting-bar H, the rear end of which is threaded to engagewith a nut I, the latter being adapted to be pivotally connected to theshaking-strap B of the grate, as shown in Fig. 6.

J is an actuating-lever which is designed to slide through the cored armF of the bracket F and into the connecting-bar H, as is shown in Fig. 2.The inner end of the lever Jis provided with a head j, preferablytapered as shown, and of sufficient size to prevent the lever beingwithdrawn through the bracket while it will easily enter and slidewithin the hollow connecting-bar H. The outer end of the lever may beprovided with any suitable handle J. 7

The parts being constructed and arranged substantially in the mannerherein shown and described, the operation is as follows, reference beingspecially had to Figs. 2 and 6: The actuating-lever is pushed in whereit is entirely out of the way when drawing ashes from the ash-pit. Itbeing desired to rock the grates-the ash-pit door is opened, theactuating lever is then drawn out, and by oscillating this lever thegrates are rocked in the bearings through the connections between thesaid lever and the shaking-strap B, as can readily be seen by referringto the drawings. The grates having been rocked, the actuatinglever ispushed in, as shown in Fig. 2, and as the lever passes through thebracket and the yoke, as shown in said figure, it will readily be seenthat the grates are thus locked to their level position or to theposition to which they may have been set at the time of attaching theshaking device to place.

It is evident that the device maytake on various forms in detail ofconstruction and as may be necessary in applying it to different 9styles of rocking grates and still be within the spirit of my invention.

What I claim as my invention is In a shaking attachment, in combination,a vibrating bracket provided with a hollow ICO mm, a hollow barconnecting said vibrating bracket with the shaking-strap of a rockinggrate, and an actuating lever or handle adapted to slidingly engage saidbracket and said hollow connecting-bar for the purpose of locking thegrates to their adjusted positions, substantially as herein described.

I In testimony whereofl afiix my signature, in presence of twowitnesses, this 4th day of ()ctober, 1890.
